Electrical connector
An electrical connector comprises an insulation body, a plurality of terminals, and an elastic part; the insulation body is provided with the first and the second sidewalls oppositing to each other; an accommodation space being formed and enclosed in the first and second sidewalls for accommodating a chip module. Each terminal is accommodated in the insulation body and is provided with an elastic arm protruding and stretching into the accommodation space; the elastic arm is provided with a contact portion for contacting an electrically conductive slice of the chip module. The elastic part is accommodated in the insulation body and used to precisely locate the electrically conductive slice and the contact portion. Being pressed downwards, the electrically conductive slice of the chip module presses the elastic arm, and the elastic arm bends toward the second sidewall and deforms, so that the chip module moves toward the second sidewall.
1. Field of the Invention
This invention relates to an electrical connector and particularly to an electrical connector electrically connecting a chip module to a PCB, in which an elastic part is located in an insulation body to precisely locate the chip module and terminals disposed in the insulation body.
2. Description of Related Art
Currently, an electrical connector connects a chip module to a PCB, as shown in
Thus, a new type of an electrical connector is necessary to prevent the defect mentioned above.
Consequently, because of the technical defect described above, the applicant keeps on carving unflaggingly through wholehearted experience and develop the present invention, which can effectively improve the defect described above.
SUMMARY OF THE INVENTIONIn this invention, an electrical connector is provided with an elastic part making a precise location between a chip module and terminals in an insulation body.
The electrical connector according to this invention, which is used to electrically connect the chip module to a PCB, comprises an insulation body, a plurality of terminals accommodated in the insulation body, and an elastic part accommodated in the insulation body. The insulation body is provided with a first sidewall and a second sidewall that are opposite to each other, and an accommodation space for a chip module is formed and enclosed in the first and second sidewalls. Each terminal is provided with an elastic arm that is protruding and stretching into the accommodation space, and the elastic arm is provided with a contact portion contacting an electrically conductive slice of the chip module. The elastic part is used to precisely locate the electrically conductive slice and the contact portion.
Thus, when the chip module is pressed downwards, the electrically conductive slice of the chip module pushes down the elastic arm of the terminal. When being pressed, the elastic arm bends toward the second sidewall and deforms, which causes the chip module to move toward the second sidewall. The elastic part is near the second sidewall and thus the chip module directly lean against the elastic part so as to prevent the chip module from directly leaning against the second sidewall; thereby the chip module appropriately moves toward the first sidewall for precise location between the electrically conductive slice and the contact portion.
Now, the present invention will be described more specifically with the following embodiments together with the appended drawings. It is to be noted that the following descriptions of preferred embodiments of this invention are presented herein for purpose of illustration and description only; it is not intended to be exhaustive or to be limited to the precise form disclosed.
In the description mentioned above, only the detailed description and drawings of the embodiments of this invention are provided without limit to this invention and the characteristics of this invention.
With reference to
Each terminal 20 comprises a wedge part 21 accommodated in the terminal accommodation hole 11, and an elastic arm 22 stretching from the wedge part 21. The elastic arm 22 is lengthwise, located in the accommodation space 14, and provided with a contact portion 221 contacting an electrically conductive slice 41 of the chip module 40.
Further, the electrical connector 1 is provided with an elastic part 30 accommodated in the insulation body 10. The elastic part 30 lies at a side toward which the elastic arm 22 of terminal 20 stretches and the elastic part 30 leans against the second sidewall 13 of the insulation body 10. The elastic part 30 comprises a holding part 31 accommodated in the insulation body 10, and a supporting part 32 stretching from the holding part 31.
With reference to
As shown in
Thus, when the chip module 40 leans against the second sidewall 13, the transversally moving distance for the contact portion 221 of the terminal 20 is defined as A and the maximum moving distance for the chip module 40 in the transversally direction is defined as A1, namely the distance from the second sidewall 13 to the sidewall of chip module 40, and thereby the chip module 40 is just right arranged between the first sidewall 12 and the elastic part 30.
While the invention has been described in terms of what is presently considered to be the most practical and preferred embodiments, it is to be understood that the invention needs not be limited to the disclosed embodiment.
On the contrary, it is intended to cover various modifications and similar arrangements included within the spirit and scope of the appended claims which are to be accorded with the broadest interpretation so as to encompass all such modifications and similar structures.
